I think this is due to setting up (or attempting to setup) facebook login, which doesn't work. But now i cannot create a new member, nor can i register one. When i attempt to register, captcha fails. When i try to create a member i get this error:
EX1054
exception 'IPS\Db\Exception' with message 'Unknown column 'fb_lastsync' in 'field list'' in /var/www/truradio/system/Db/Db.php:359

#8 {main} This is true even if i disable facebook login. Looking at the DB, i see that core_members doesn't have a field named fb_lastsync. Also, while your in there, core_member_ranks doesn't have the "use_icon" or the "icon" field ... at least in my DB. Which causes creating or editing ranks to fail. This is an upgraded to beta board from 3.4.

​Theoretically, the workaround (at least in 3) is to use galleries (my media option) in a post to get an accurate thumbnail, but it's a lot of clicks to get to the full size image. And, of course use image magick instead of GD 2...

Looks like GD does strip the profile at least in gallery, while image magick retains it. Not sure what the forum in 3 is using to re-sample the images, but it seems like it's just the GD 2 library since it strips out profiles in post attachments. Guess i could trance it in a debug or sift through the code. Either way, it would be nice to have the option of using image magick across all modules, not just the gallery.

This is basically a GD or image magick script, not sure why it's not utilized in 4? It's obviously a setting in the admin... As far as profiles, pretty sure if you use the image magick instead, it retains the profile or should, by default. Not sure how GD works, never needed to code for it.

I run my site from the box to the wiring so IPB has helped out a ton there. We used to use phpBB and as much of a pain it was to manage, it did have a ton of development behind it. What's mostly lacking in IPC is the documentation. Regardless, i continue to tinker around with all the features and tools which make management much simpler overall. I have yet to move from the standard skins, but most of our members enjoy the clean look and easy navigation.
